Description

Multifunctional vocal cord polyp forceps

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a multi-functional vocal cord polyp pincers.

Background

Vocal cord polyps are very common diseases in the otolaryngological department, are mostly caused by excessive use of throat and improper sounding, and are mainly manifested as hoarseness. The outpatient service can carry out the electronic laryngoscope operation under the local anesthesia, but the cooperation of patients is needed, and the operation effect can be influenced. After hospitalization, the operation can be performed under the laryngoscopic support under general anesthesia, the operation is required to be performed under the direct vision of naked eyes, and the operation with the enlarged visual field under a microscope can be performed in recent years.

Even if the patient is completely matched, the patient can still tolerate the mild and pedicle-carrying polyp which can be cut off at one time; however, patients have difficulty in matching with huge or broad-base polyps with difficult disposable excision, and unclean disposable excision increases the risk of recurrence. Therefore, the general anesthesia under-support laryngoscope operation is still the preferred scheme for vocal cord polyp excision.

When the operation is performed under the general anesthesia support laryngoscope, the operation has higher requirement on the position of a patient, the patient needs to go to a pillow and lie on back, and the vocal cords are exposed in the whole course only if the position is available; however, for the patient with a high larynx, even if the position is the same, the vocal cords are still exposed during the whole process, especially the anterior vocal cords combination, so that the operation risk is increased undoubtedly, and the operation duration is prolonged.

When the existing visual anesthetic lens is applied to general anesthesia operation, the visual anesthetic lens can be connected with a display screen, and meanwhile, because the visual anesthetic lens has a certain physiological radian, the requirement on the body position of a patient is low, the glottis of the patient can be completely exposed, and the visual anesthetic lens is widely applied to patients with difficult intubation.

As the surgical operation instruments matched with the traditional laryngoscope are straight and cannot be operated under the visual anesthetic scope, the polyp resection device required to be used is also bent at a certain angle and is adaptive to the visual anesthetic scope. And the opening angle of the forceps head of the existing polyp forceps can be controlled only through the experience of an operator, and no strict reference standard exists.

During surgery, blood or saliva needs to be attracted to prevent affecting the resection of polyps. Traditionally, the polyp forceps are removed from the laryngoscope and the suction tube is inserted into the laryngoscope. The use mode is more complicated.

Therefore, it is an important research direction to provide a polyp forceps which is suitable for a visual anesthetic scope, is convenient to use, can control the opening angle of a forceps head, and provides an operator with an easier operation tool.
